Do you think Cone Carbon Sepia and MIS Eboni are not 100% carbon pigment inksets in the sense that the image forming substance includes some colorants?  

The Aardenburg-Imaging fade test results certainly look very different than the blended B&W inksets tested.  I've summarized the 20 MLux-Hr midtone results here:

Note particularly the change in the Lab A values.

I think these test results are most consistent with the 2 carbon inksets shown (Cone Carbon Sepia and MIS Eboni MK-3) being, in fact, composed of carbon pigments with no colorants added.
